A new earthworks guide will help residents and developers navigate new regional water plan changes that strengthen water discharge management.

Otago Regional Council (ORC) senior environmental officer Melanie Heather said any earthworks projects in Otago, including small-scale works, will need to meet the new regulations and consents may be required.

“Having a clear plan for erosion and sediment control, getting the right consents and then remaining compliant, protects you, your property and the environment,” she said.

Melanie said the ORC compliance team has developed the new guide to provide context to the council’s residential earthworks provisions, consenting information and compliance.

The guide includes content required for any environmental management plans and erosion and sediment control plans, which are required for most of the consents granted by the ORC.

“Earthworks activities, if not managed properly, can lead to soil loss into waterways which can be detrimental to ecosystems and water quality,” she said.

“It’s important to follow erosion and sediment control best practice guidance to minimise the adverse effects of erosion and sediment throughout your project.”

There have been past instances around Otago where sediment was flushed off earthwork sites into nearby creeks, streams and lakes following rainfall, in some cases leading to prosecution.

The main changes to the water discharge rules apply to property developers, Melanie said.

The regional plan’s rule 14.5 sets new, higher standards for earthworks to qualify as a permitted activity.
